In particular, we develop software tools that vis- ually demonstrate relevant wireless communications parameters and processes, including those already taught in undergraduate communications courses (e.g., power, coding rate, modulation type, data rate and bandwidth) to students in an interactive way. We exploit our Internet- accessible wireless communication testbed CORNET to enable students to experience wireless communication challenges and learn different solutions in realistic environments via an ordinary web browser. This paper presents our approach to authentic STEM learning and compares it with other past and ongoing initiatives. We conclude that there is a gap of practical teaching tools and methods for educating students as well as radio engineers and researchers about new trends in wireless communications with a focus on spectrum sharing. 1 Introduction Wireless communications research is investigating how to make better use of the radio frequency (RF) spectrum. Increasing the throughput per unit bandwidth (spectral efficiency) is a popular choice that is continuously improved and employed in practice. Reusing frequency bands oppor- tunistically (dynamic spectrum access or DSA) is still in the research phase, but is likely to make its transition to practice in the near future based on the currently ongoing license auctions for the AWS-3 and other bands in the United States. These techniques are covered in graduate-level electrical engineering classes, but cannot easily be introduced to undergraduate students. Undergraduate engineering students struggle with the basic concepts in wireless communications. We therefore propose the development of visualiza- tion and gamification tools to be used in undergraduate courses. Gamification refers to the use of game design elements in non-game contexts, products, and services1,2. Gamification is also con- sidered a useful tool to motivate and enhance learning. To apply gamification to educate about basic and modern wireless communications principles,
